| Most of the arthropods consist of an infill of sparry calcite with uniform luminescence. |
| Polygonal septarian cracks are filled with sparry calcite cements or micrite matrix. |
| Cliffs of sparry limestone rise in the rear of the site we had selected, to an elevation of near three hundred feet. |
| The compact carbonate of iron has no relation externally with the sparry variety. |
| In cooling, one exhibits a sparry, crystalline structure, the other that of clay. |
